Pneumatic volume-flow controller

Suitable for use in potentially explosive atmospheres in zone 1 II 2 G T6

Conformity tested as per EN 13463-1 and EN 1127-1 (potentially explosive atmosphere 1 II 2 G T6)

Controls constant, switchable or variable air volumes

High-precision, static differential pressure sensor with large measuring range (1…160 Pa)

Front plate printed with circuit diagrams for easy identification of the controller functions

Compressed-air connections with Rp⅛” female thread

Special measuring connection for detecting the volume flow

Low-pressure connections with dual-diameter connector for soft plastic tubing (internal Ø 4 and 6 mm)

2 inputs

• Command variable

• Setpoint shift Δ

2 outputs

• Actual value

• Control of damper actuator

1 adjuster for calibrating the sensor measuring range

3 setpoint adjusters for maximum and minimum limitation of volume flow and for limiting the setpoint shift Δ to max. ±20%
